Hi,
When you create a project there is an example called "Keyboard Example" under the "UI template" section. You can have a look at the code and its configuration to re use it in your project. I believe some users have shared some of their own on this forum or online.
It is in our backlog to create a more adaptable keyboard widget and to add it directly to Designer but it is actually quite complex as every project have different needs.
